MOUNTING ron nYEGLnssEs.

Be it known that I, J. MARTEL, of Laconia, in the county of NewHampshire, have-invented certain new and useful Improvements inMountings for Eyeglasses, of which the following is a specication.

This invention relates to the type of eyeg rigid bridge connects thelenses and rests upon the nose and to this bridge are pivoted the leversof finger pieces.

Thisinvention is of the type shown in my application for patent oneyeglass mounting,

EDGAR :led February 15, l1918, Serial No. 217 ,399.

The present invention is intended to provide roller-bearings orball-bearings of the type consisting of a plurality ofv rollableinannular form to reduce the friction and therefore the wear of theparts.

Preferably such rollable members are located in the bridge,

there is more room, but

bridge up through the finger piece lever or between a pin or upward`extension of the bridge and the finger piece lever.

I-Ieretofore it has not been considered possible to provideroller-bearings for the finger piece type of eyeglasses on account ofthe small size of the parts, but with my arrangement, such bearings areperfectly practical. Figure 1 is -a plan view 'of a pair of eyeglasseswithnger piece levers embodying my invention. Fig. 2 is a section online 2-2 of Fig. 1, very much enlarged` showing my preferred form ofmounting. Fig. 3 is a f section on line 3--3 of Fig.

- glass mounting's.

2. Fig. 4 shows, two types of rollable bearings. Figs. 5, 6, 7, 8, 9 and10 are sectional views similar to Fig. 2 showing diierent applicationsof my rollable bearings to eyein perspective,

viewof the type of rollable member shown Yin Fig-1o. v v

G, G represent the lenses, H, 'H represent the lens clamps which areconnected together In Figs. 2 and by the bridge B.

In all the views, B represents the bridge, and S represents thereturning spring of well known type. f

3, I show a'pivot hole 14 countersunk in bridge B and in' the center ofthis a hole 10 which extends through the Specification of LettersPatent.

'end at 13 is threaded .to receive the threaded bridge and isfi'threadedto receive the" nut 17 havingat its upper end an annular rim 18 to holdinplace spring S, as shown;

rIhe linger piece'lever L has a downwardly depending tubular extensionforming a pivot member 16 through which and through the lever extends ahole 9 ywhichfis preferably of suiiicient size .so that the smooth part12 of pin P will be'out of contact therewith.

Pin P is first screwed in place in bridge B, after which a plurality ofrollable members 15 are put in place around the rim of hole .14', andthen finger piece leverL and tubular eX- tension 16 are passed over pinPand downward until tubular extension 16 bears against members 15.Members 15 can be held in position while 'assem lingby the use cfalittle' oil or similar substance.- u Spring S andvnut 17 are then put inplace and the other end of pin P is upset at 19 to prevent the partsfrom getting out of position. Preferablythe lower end of pin P is upsetat 8. f Y

In Fig. 4 is shown a rollable member 15 of cylindrical form and at 2 6is also shown a rollable member of spherical form lof the usual balltype for ball-bearings. In Fig. 5, bridge B is bored with a central pinhole 10 threaded to receive the shank 20 of retaining pin R, and with asomewhat larger hole 24 to permit the pivot member shown as tubularextension 16 of lever L to enter, and a still larger ball retaining orpivot hole 25 to receive the spherical balls 26. The pin It has athreaded shank 20, a smooth shank 21, which is preferably slightlysmaller than hole 9 through lever L, and an annular shoulder 22,together with a' cap 23 to hold in place thespring S. The'ballbearings26 preferably bear on the outside of 16 and the underside of the fingerpiece i leverL. A. y n

In Fig. 6, I show a pin R .similar to that sho'wn in Fig. 5,but bridge Bis counterbored witha single bearing hole 31 similar to 14. The ,tubularextension 30 of finger piece lever M, however, is of larger diameter andthere is sufiicient clearance between it and the smooth shank 21 of pinR to permit the rollable members in the form yof cylinders 15 to beinserted between.v` The -piece lever. y[.`he pn also serres the purposeofretainingatheparts inplaee and may be upsetat 2.7.if desired.
